President Trump ended his Twitter silence on his first full day back in the U.S. by attacking the "fake news media."

"It is my opinion that many of the leaks coming out of the White House are fabricated lies made up by the #FakeNews media," Trump tweeted Sunday morning.

"Whenever you see the words ‘sources say' in the fake news media, and they don't mention names it is very possible that those sources don't exist but are made up by fake news writers," he continued.

"#FakeNews is the enemy!"

In February, Trump accused reporters of making up stories and sources that were critical of him.

"They shouldn't be allowed to use sources unless they use somebody's name," he told the Conservative Political Action Conference. "Let their name be put out there."

Trump's attacks on the media come as his campaign team faces increased scrutiny over its contacts with Russia.

Members of Trump's White House have regularly requested anonymity when speaking to the press.

Trump continued his media critique by saying, "Does anyone notice how the Montana Congressional race was such a big deal to Dems & Fake News until the Republican won? V was poorly covered."

Republican candidate Greg Gianforte won the special election Wednesday, after he allegedly body slammed Guardian reporter Ben Jacobs. Gianforte has been cited with misdemeanor assault for the incident.
